Now that the default value for this flag is true, we should remove it altogether.

Too soon. We need to be able to turn off for testing, to see what you broke.

While I'm in no rush to land this, I want to point out that the changes that are actually guarded by that flag are not very risky compared to the GraphicsLayerCA changes that were related to supporting animation of those properties and which are not guarded by that flag (such as r268483).

We leave flags around for a year for testing.

Thats not a policy I have heard before. It seems kinda reasonable, though I am a bit unclear its actually useful. If we are going to go with this, it would be nice to make this more official, and have some way of following up (since we have tons of flags that should be removed, but never have been). Can you propose a model for how we can ensure we revisit these after a year?
